I plan on getting headers and HFC to go with my exhaust and intake. and I keep reading that our cars like to running rich or lean, i forgot. Is this a way to adjust the a/f curves ourselves without having to get our ecu reflashed by a shop when dyno'ing.

main reasoning behind this is I'm not planning on getting a dyno done for a while and i don't want to run into engine problems with these mods. and I don't want to have my ecu reflashed. What other options do I have piggyback wise that I could do, or that a shop has to do. (i guess)

 

i just picked up a neo the other day and was wondering the same thing you are....i'll keep you posted as far as the install and the tune goes. like you said, i got headers, intake, cat-back, and hfc on the way so results should be simillar. i'll keep in touch

 

thanks
